Gregarines are symbionts of the gut or other body cavities associated with numerous insect species. Knowledge about natural gregarine infection levels and across metamorphosis in holometabolous hosts is sparse. Individuals […]
Key points Seafloor hotspots and 7,252 new benthic invertebrates have been described since the publication of the second World Ocean Assessment, and there has been a five-fold increase in critically […]
Mercury (Hg) can negatively affect marine biota through uptake from prey and from the surrounding environment. Cephalopods constitute a major prey group in Southern Ocean ecosystems, yet little is known […]
Recent decades have seen record-high temperatures on the Antarctic Peninsula (AP) due to combined atmospheric rivers (ARs) and föhn warming. While ARs frequently enhance föhn, not all events cause surface […]
As heatwaves increase in both frequency and intensity globally, the need to develop tools to predict the human impact and develop a more comprehensive understanding of the impact mechanism at […]
Recent sub-ice topography investigations have imaged—with greatly improved detail—a set of low-elevation V-shaped basins hidden beneath a very large sector of the East Antarctic Ice Sheet. Here we jointly interpret […]
The marine biological carbon cycle plays a crucial role in the sinking and sequestration of atmospheric carbon and in regulating the global climate. Most existing research on biological carbon sequestration […]
Assessing extinction risk is important for protecting species, as it is the starting point for conservation efforts. However, in Antarctica, none of the c. 116 species of bryophytes (the main […]
Extreme environmental events (EEEs) in Antarctica and the Southern Ocean are occurring with growing frequency and severity, and will become more pronounced under continued global warming. Antarctic research relies on […]
The springtime variability of the stratospheric polar vortex over Antarctica is an important source of predictability for the Southern Annular Mode (SAM) and associated Southern Hemisphere (SH) regional climate anomalies […]
The dependence of aeolian dust transport on atmospheric circulation patterns allows dust preserved in Antarctic ice cores to serve as a proxy for past circulation variability. Here, we investigate dust […]
The mesosphere and lower thermosphere (MLT) dynamics play a crucial role in the vertical coupling of the whole atmosphere and are a key component of space weather processes. However, accurately […]
